Answer:
181/65
Step-by-step explanation:
If cos theta is 5/13 then sin theta is equal to 12/13. This is because 5 squared (25) + 12 squared (144) = thirteen squared (169). Tan is sin/cos or opposite/adjacent, so it is equal to 12/5. To add 12/5 and 5/13 you need a common denominator, 65 in this case. 12 times 13 = 156 and 5 times 5 = 25. 156 + 25 = 181. Final answer is 181/65.
